  1. Although I had a few issues with the video as well, I'm hoping it'll spread the word about recapping some, especially seeing how big his audience is on YouTube. It seems that a lot of people into classic Macs still don't realize just how damaging caps can be. Re: the twisting caps method, respectfully, I don't think it's as dangerous as people make it out to be. Although a newcomer to the hobby might not know the difference, if your board is still in "okay" shape, it works fine, provided that you're gentle (based off purely empirical evidence, 5x 68k's of mine). Also bear in mind that the heat from desoldering can damage pads too. I totally agree with your points on lack of ESD safety & the dishwasher though, it was frustrating to see that in the video.

    It appears you can get both the SCC and SCSI controller off eBay for roughly $10 each (not my listings). BTW, when buying obsolete parts like these, it's wise not to buy from sellers in China as they have a reputation for relabelling parts as others.

    Thread for anything about the LC series (continued)

    I don't mean to be rude, but you haven't created some "System 6 for Windows" thing; you've bundled Mini vMac, an open source emulator that most, if not all of the members here are well aware of, with a copyrighted ROM/OS, property of Apple. It's hardly anything new.

    I'm pretty sure that you would at least get a raster on the display if the SCSI and/or SCC chips were bad. After seeing all the crud that was under the Bourns filters, though, I'm wondering if there's more under one of those chips and it's shorting some signals together.

    Mac LC Weirdness - Electric Charge? Shorting Out?

    Almost certainly a power supply issue, then, given that the hard drive starts spinning down.

    I've never heard of it failing, but maybe try swapping that big socketed VLSI chip next to the CPU, just to rule it out (just be very gentle to prevent cracking the socket). Also, maybe there's a rotted trace under the SCC or SCSI chip?

    Mac LC Weirdness - Electric Charge? Shorting Out?

    What exactly happened when the computer "shorted out"? This sort of sounds like a PSU problem. Was every cap in the PSU replaced? Some guides say to only replace a few, which is false.

    Noisy Fan, flaky power switch in my LC III

    Thank you, my mistake.

    Noisy Fan, flaky power switch in my LC III

    The power switch, at least on my PSU, has a few wires soldered to it and is clipped into the back of the metal case.
  10. Sounds like a really nice machine, but given that it isn't recapped I'd probably say closer to $150-$200. The SE/30 is almost infamous for cap issues.

    Color Classic no power issue debunked!

    10uF is way too high for an oscillator circuit like this, try a 33pF cap.

    Come to think of it, I have a 604 card and some of the SMD electrolytics right next to/under the heatsink seem to be bulged on top. The card still works, though.

    Also, make sure the processor card has clean contacts and is fully seated in the slot (it takes a lot of force to put in all the way and this got me on my 8500). 8100/8200s don't have processor cards and AFAIK the later 8600/9600 ones aren't compatible.

    Weird... just guessing, maybe the battery leak damaged the ROM sockets and reseating the chips broke another one of the connections?

    Astec PSU Question

    Just wanted to ask before ordering new caps: is there any reason to recap these PSUs rather than replace them with modern ATX ones? Are the original PSUs reliable once recapped, or are they still failure-prone?
